Connecting Breakout Box

As the pins on the connector of the Electronic Control Unit (ECU) are sealed on the connection side, it is not possible to carry out measurements in the usual way during fault-tracing.

Breakout box (BOB) 86 11 006 with wiring 86 11 030, which is connected between the connector and ECU and brings the measuring points out to numbered sockets for convenient measurement, is used instead.

All measurements on the system are performed with the breakout box connected.

WARNING: It is absolutely prohibited to use the breakout box when driving the car. Remember that the brake system is a safety system!
